The output policy maps are as follows:
! Each class maps to a different qos-group with
! class-default taking any traffic not assigned to a qos-group
! Note: in this example, the outbound policy map drops voice packets when the priority
queue exceeds 33% utilization of the link. Each deployment must establish their own upper
bound for voice packets.
